I have a problem with the IRB 4600 robot, using the IRC5 controller. I calibrated my robot as it should be, but when I try to move it linearly, it gives me the error shown in the image 1. This happens regardless of the robot’s position.

This probably happens because two axes (I guess 4 and 6) are parallel or coincident. Try to manually jog all axes to a few degrees different from 0 first, before jogging linearly. Do you still get this error after that?
Hi,
Thanks for answering me. I moved the robot but the problem is the same.
Four and six are in line or too near to it when axis 5 is near zero. Move axis five away from zero and try again.
Thanks the problem was solved.
